◆ _ksba_cms_add_cert()

gpg_error_t _ksba_cms_add_cert	(	ksba_cms_t	cms,
		ksba_cert_t	cert
	)

ksba_cms_add_cert: @cms: A CMS object @cert: A certificate to be send along with the signed data.

This functions adds a certificate to the list of certificates send along with the signed data. Using this is optional but it is very common to include at least the certificate of the signer it self.

Return value: 0 on success or an error code.
